High Availability for DB2 on AWS

If you're running an IBM product that requires a DB2 backend, you should really consider running DB2 on AWS. Here's a great article that provides you with the CloudFormation template to set it all up for you very quickly:

If you're concerned about running your infrastructure in the cloud, please contact us so we can give you the information you need about the tight security and incredible flexibility that AWS provides.

Update 8/8/2023: One important note: this still uses TSAM for failover. What this means is that if your primary DB2 instance has a problem, the entire VM hosting that instance is rebooted. So if you have multiple databases on that instance, they're all failing over to the backup. If you have any other processes running on that VM, they're all going away. You can definitely architect your application to work fine with this, but it is definitely something you have to keep in mind before simply implementing DB2 HADR.
